MINIATURE-CASE. V

Specification of Letters Patent No. 14,501, dated March 25, 1856.

T0 all whom t may concern.'

Be it known that I, HALvoR HALvoRsoN, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Miniature- Cases; and I do hereby declare that the sameis fully described and represented in the following specification andthe accompanying drawings, letters, figures, and references thereof.

Of the said drawings, Figure, l, represents a view of the interior ofone of my improved miniature cases as it appears when open. Fig. 2, is alongitudinal and central section of it under such circumstances. Fig. 3,is a transverse section of it. Fig. 4, is a side view of it as closed.

The said miniature case consists of two parts A, B, hinged together at,C, and provided with a clasp, D, like the French porte monnaies incommon use. The porte monnaies referred to are made with flexibleleather sides respectively secured to surrounding frames of metal. Thiswill not answer for a miniature case, whose sides require to be made ofa stiff material such as will not yield so as to cause injury to thepicture inclosed between them. For this purpose I compose each leaf orpart A, B,

of two rectangular frames, a, Z), a sunken or dished plate, c, and aleather or embossed covering,l cl. The two outer frames, a, a, of eachhalf are hinged together and each-is provided with a lip, e, extendingentirely around its outer boundary and made to inclose the dished plate,c, and the second frame, Z), as seen in the drawings. The said plate, c,is made to project through the frames, and previously to being put inplace therein is to be covered with a layer or covering, d, of leatheror some other suitable material, embossed or not as occasion mayrequire. After they parts composing each half of the oase are arrangedas seen in the drawings, they are confined together by rivets (as seenat f, f, &c.) made to pass through them.

As miniature cases are usually finished, withanother rectangular frame,g, eXtending around within one of the parts and covered with velvet forthe purpose of securely holding the picture and the glass coveringthereof in place, it is found to be very difficult if not impossible toglue or cement this frame to a surrounding frame when made of metal. Inorder to accomplish this I place between the metallic dished plate, c,and the frame, Z), and previous to uniting them together a rectangularframe or piece of pasteboard, 7L, or some other equivalent material, towhose inner edge, glue or cement will readily 'and firmly adhere.

The frame, g, when put in place in the case, can be glued or cemented tothe inner edge of the said frame, z', and by such means be made toadhere to the case with great tenacity.

IVhat I claim as my invention, ish

l. The combination of the metallic dished bearing plate, c, the leatheror embossed covering, d, and the two frames, a, the whole constitutingone portion or half of the case as specified.

2. And in combination with the metallic confining frame, and the velvetcovered glass holder or frame, g, I claim the frame, h, made ofpasteboard or other equivalent and applied for the purpose as specified.

In testimony whereof I have hereto set my signature this second day ofMarch A. D. 1853.

HALVOR HALVORSON.
